Rear tyre balancing question

[Dudeofrude]

Yes, he's talking bollox.
Everything that has mass & rotates will vibrate & needs balancing, you may be unable to detect it, but it will defo vibrate if not balanced.
Personally I leave all components fitted (discs & sprocket carrier etc) achieves a better dynamic balance of all rotating parts, most tyre fitting places don't balance with sprocket carrier fitted tho.
All depends on what equipment you're using to balance a wheel.
ie) Electronic Dynamic balancer
ie) Home DIY frame type balancer
I fit & balance my own tyres & use lead bike specific weights, I have access to both types of blancers but prefer the frame type for bike wheels.
I'd never allow a tyre fitter to balance my wheels, they don't seem to give a shit about how they remove old balance weights or consider where they slap on on fugly balance weights... But then I'm OCD as F***K.

Yeah I was gutted about this myself. I have lovely gold powdercoated wheels and they go and stick two fugly lumps of grey metal on them, could have at least asked me first.
I know its superficial but you'd think they'd do coloured ones by now haha
